e history data of part test free-degree, lastly, Inverse Fast Fourier Transform is Рimplemented to the dynamic response data of reduction free-degree and the dynamic response time Рhistory data of whole free-degree of the finite element model can be obtained by inverse transform of Рreduction transform matrix, and the visual simulation of the structural vibration response pleted Рby the aid of simulation software. Calculation and simulation on a shell structure in this paper is done, Рand the results are satisfying, the feasibility and effectiveness of the researched technology is Рdemonstrated.
